Sep 7, 2010

I'm trying to override the onBackPressed() method of the ActivityGroup class:

public class MyClass extends ActivityGroup {

public void onBackPressed() {
// do something

but I'm getting the error The method onBackPressed() of type MyClass must override a superclass method. I'm relatively new to Java, I've seen here that people do it and it works for them Why I'm getting this error? I'm writing an app for android 1.5, could the problem be here?

Android :: Calling Superclass Method In Subclass Constructor

Apr 30, 2010

I get a NullPointerException calling a Superclass Method in Subclass Inner Class Constructor... What's the Deal?

In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class.


After I instantiate the object in the constructor, I get a runtime error when I try to assign a value in the inner class with a superclass method.

Can you not call superclass methods in the subclass constructor?

Android : Override A Method Taking A Reflected Class Argument

Sep 22, 2010

Since API 7, PhoneStateListener has a function: void onSignalStrengthsChanged( SignalStrength signalStrength )

Question: how can I override this via reflection so that I can stay backwards compatible with earlier APIs that don't have the SignalStrength class ? If I make the argument an Object, the signature changes of course.

Android :: Override ManagedQuery Method To Include Limit Param When Using Self-made Content Provider?

May 7, 2010

I've built my own content provider and I've run into an instance where I need to execute a query and include a limit param.

The method call to managedQuery doesn't include this param and there fore I see no way to implement this w/o somehow overriding the managedQuery method?

I've created a second query method in my content provider which accepts an additional param, the limit param but I don't think I can make the managedQuery method call this custom query method of my content provider.

What's the best way to do this?

For reference, here is my content provider class...

Android :: Method Undefined For Type SmsReciever - Context

Nov 13, 2010

I am developing an app that upon receiving an SMS message with a unique string of text, the GPS is enabled and starts tracking the location of the phone. The issue I'm having is with the getSystemService() method.
I receive the error "The method getSystemService(String) is undefined for the type SmsReceiver", I believe this is because it does not have a context. I have tried to add in a context with in my code with 'ctx', and that removes the error but my application crashes every time I run it on my phone. The code for recieving the SMS works fine, and the GPS location tracking code works fine if it's in my main class.
I still don't fully understand contexts.

Android :: Show Method Definition - Eclipse Recognizes Warning On Method

Nov 22, 2010

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

My code is as follows, I'd appreciate any help on figuring out what I did wrong since it looks correct to me.
